Abstract

A coating dispenser such as a spray gun which is particularly adapted for the application of a protective coating material onto metal can bodies comprises a gun body formed with a liquid passageway which carries the valve stem of a needle valve. In the presently preferred embodiment, the lowermost end or valve tip of the needle valve, and a valve seat, are carried within a valve seat block which is secured to the base of the gun body. A threaded connection is provided between the valve tip in the valve seat block, and the valve stem within the gun body, so that the valve tip, valve seat and valve seat block can be removed and replaced as a unit when the valve tip and/or valve seat become worn. Pins connected to the valve stem, and to the valve tip, are carried within slots in the gun body and valve seat block, respec-tively. These pins prevent rotation of the valve stem relative to the gun body and the valve tip relative to the valve seat block when they are threaded into and out of engagement with one another.
